A Geometrically Inspired Model for Brittle Damage in Compressible Elastomers
, 2021Regularized continuum damage models such as those based on an order parameter (phase field) have been extensively used to characterize brittle damage of compressible elastomers.

Due to the existence of true three-dimensional high-geostress in deep underground engineering, rock shows different mechanical properties and brittle–ductile behaviours from conventional triaxial stress states, however, the different characteristics of ...

Damage-Resistant Brittle Coatings
Advanced Engineering Materials, 2000Laminate structures consisting of hard, brittle coatings andsoft, tough substrates are important in a wide variety of engi-neering applications (cutting tools, electronic multilayers, la-minated windscreens), biological structures (teeth and dentalcrowns, shells, bones), and traditional pottery (ceramicglazes).

Dynamic Behavior of Damaged Brittle Solids
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1999AbstractThe macroscopic dynamic behavior of damaged brittle solids is investigated. Special attention is devoted to the analysis of wave attenuation and dispersion in micro‐cracked solids. Several methods are discussed and numerical examples are presented, to show the dependence of the wave attenuation coefficient and the effective wave velocity in ...

Size effect analysis of quasi-brittle fracture with localizing gradient damage model
International journal of damage mechanics, 2021The size effect of a quasi-brittle fracture is associated with the size of fracture process zone relative to the structural characteristic length. In numerical simulations using damage models, the nonlocal enhancement is commonly adopted to regularize ...

Progressive Damage in Quasi-brittle Solids
2020We present a model of material degradation relying upon a local damage law supplemented by convex constraints. This results in a damage model with bounded variation that is shown to share the same features of the so-called Thick Level Set approach. Unlike the original model, in the present formulation the level set-based representation is abandoned in ...

Interaction between interfacial damage and crack propagation in quasi-brittle materials
Mechanics of Advanced Materials and Structures, 2021A thermodynamically consistent phase field formulation for modeling the interactions between interfacial damage and bulk brittle fracture is presented. A regularization scheme is considered for both the interface and the crack phase field.

Validating Theories for Brittle Damage
Metallurgical and Materials Transactions A, 2007Validating simulated predictions of internal damage within armor ceramics is preferable to simply assessing a model’s ability to predict penetration depth, especially if one hopes to perform subsequent “second strike” analyses. We present the results of a study in which crack networks are seeded by using a statistically perturbed strength, the median ...

A continuum damage-based three-dimensional fracture simulation method for brittle-like materials
International journal of damage mechanics, 2021Current numerical methods cannot simulate well three-dimensional (3D) fracture process of solids. In order to study 3D fracture process of brittle-like materials and improve crack growth path prediction accuracy, a method is developed based on continuum ...
